Sergeant Donkey, also known as "Donk", is a Systems Alliance soldier assigned to Unit 212's Dog Squad on Eden Prime. He has carnal desires for fellow squadmate Ashley Williams and tries his best to make her sleep with him. Two days before the geth attack on Eden Prime, Donk and his squadmates were on downtime fooling around at a bar. He tries seducing Ashley over drinks, but his other squadmates scoff at his chances and even joke that there's a better chance of Ashley hooking up with Pennyloafer, the other girl on the squad, than with him.
